Stella Congreve, countess of Liddertal, the daughter of Baron Otto de Congreve, was an aristocrat in the court of the Nilfgaardian emperor. She was charged with the care and education of the false Ciri at Darn Rowan.
- Congreve, Estella vel Stella, – The daughter of Otto of Congreve, married to the old Count Liddertal. Upon the death of the latter, rapidly recovered, managed her inheritance most judiciously, amassing for herself a not inconsiderable fortune. Enjoying the esteem of the emperor Emhyr var Emreis [sic], she was considered a person of great importance by the court. While she had no official duties, it was generally believed that the emperor was in the habit of paying considerable attention to her words and opinions. Because of her close personal relationship with the young Empress Cirilla Fiona [sic], whom she loved like her own daughter, she was jokingly referred to as the "Imperial mother-in-law". She outlived both the Emperor and the Empress, and died in 1331; as to her huge fortune, it fell to distant relatives on the Liddertal side of the family, called the Whites; being stupid and short-sighted, they squandered every bit of their inheritance.
